Wake on Demand requires an Apple AirPort Base Station or Time Capsule
with firmware 7.4.2 or later installed. To use Wake on Demand
wirelessly with a WPA or WPA2 network, the AirPort base station or
Time Capsule must be hosting the network.

okay, wake on demand is on, but which app (and further settings) on your iPhone/iPad can you use to connect with your mac, and still have the mac still password-protected when waking?

You need something that can send the appropriate network packet to wake up the machine. Apples routers (I have a Time Capsule) can proxy Bonjour-announced services while the machine is sleeping and can wake up the machine when the proxied service is accessed. Apple also has a "Back to my Mac" feature, which I do not know if the iPad supports.

I do not think you can do what you want with your combination of sleeping devices and router hardware.
